To alljzphom "it may concertar, Y v f Beit-'known that 1', CLARENCE T. CRocKER, l Ain; "citizen of the United "States, 4residing at orwood, inthecounty of Hamilton and 5 Y Statevof Ohio, 'have invented certain new.`

and'u'seful Improvementsin Connectors, of

' ,which the following isa' `u'll, clear, and exact specification.

` My invention 'relates to connectors or couplers forjelectric cables-or conductors.

" It hasfor'oneof its objects toprovide a good connector orf'coupl'er of few parts.V which canbe easily and cheaplyl made and which are duplicateor interchaiigeable.

A further object is 'to provide aconnector or coupler consisting of part-s which can be very rated.v

' "My invention" consists inf-the, details of' constructionandin the combination and arrangements of, partsdescribedin the speciication and set'- forthv in the appended claims.

Referring now to the figures of the drawing I have shown at 10 two similar, counter; part or interchangeable terminal members, in thisca'se tubular or cylindrical in shape, each haw'fing at one end a socket to receive a conductor 11. The opposite ends of the terminal members are beveled, forming long contact extensions 12 having flat faces adapt-1 15.0 `ed tol be clamped tightly to form a connection of negligible resistance.

twist or turn both sleeves 13 relative to the terminal members. As the sleeves are rolfengage the heads of thc rivets or pins 17 m'oving the latter and hence the terminal members longitudinally toward eachother until the faces of thctcrminal members are tightly clamped together. The positions of the sleeves relative to the pins or'screws 14 and 17 after the terminals are clamped to gether, are shown in Fig. 2.V 'lhe mclination of the sides of the cam slots and hence sary to clamp the terminals together can be made any desired amount. To disconnect the termina-ls all that is necessary is torotate the sleeves in the opposite direction until the heads ofv the pins or rivets 17 reach' the enlarged portions of the" slots 16.

'This construction possesses many advantages, amon which, and short space of time iriwhich, the

is seen that the set screw 1-1 prevents the sleeve or' tube' from being moved length-i'` -wise of the terminal and hencefrom being@ i separated therefrom when the. terminalsr are Y disconnected.
